Figure P 41.41 shows the first few energy levels of the lithium atom. Make a table showing all the allowed transitions in the emission spectrum. For each transition, indicate

a. The wavelength, in nm.

b. Whether the transition is in the infrared, the visible, or the ultraviolet spectral region.

c. Whether or not the transition would be observed in the lithium absorption spectrum.
